Peculiarities
Pistol shrimps have many peculiarities. Some of them are as follows.

  • They have two snapping claws, one shorter than the other. They use them to create cavitation bubbles and snapping sounds. The snapping sound 210 DB louder, louder than a gunshot.
  • The bubbles created by cavitation are hotter than lava and move at a high speed, 60 miles per hour.
  • They use their snapping claws to stun predators.
  • Produce snapping sounds to attract their mate.
  • They have a symbiotic relationship with gobbies. Goby fish helps to protect them, and they share their food and shelter.
  • Climate change experts use their snapping behavior to detect the habitat’s health, changes in the ecosystem, and restoration.

Is Candy Cane Pistol Shrimp Safe for Reef Tank?

Candy cane pistol shrimps are reef-safe and behave like a good tank mate. They don’t hunt for mates until they are very small. Moreover, their powerful snap doesn’t pose any threat to the reef tank’s glass. Here is a brief explanation of different aspects to keep them in the tank.

Reef-Safe

They are scavengers and not a serious threat to the tank ecosystem. They used to create unique tunnels with their snappers in the substrate. However, they can be a little problem for near-substrate delicate corals due to their sand-shifting behavior.

Solo or Community Tank

They go well in both aspects. In solo, you need to establish the tank with thick substrate to satisfy their burrowing habit. Add many hiding places, e.g., rocks, caves, tree trucks, etc., to mimic their natural habitat.

On the other hand, they go well with tank mates. You should add them first so they can establish their territory. Moreover, add size and behavior-compatible tank mates, i.e., peaceful fish that are not bottom dwellers.

Gobby fish are the most suitable ones, i.e., gobby fish. It acts like a watchman for the shrimps, and Candy Cane shrimp shares food and shelter with Gobby. Neon gobies, pygmy gobies, neon cardinalfish, Small snails, hermit crabs, and other non-predatory invertebrates are a few more suitable tank mates for them.

Are They Aggressive?

They are peaceful when they are kept with other peaceful fish, especially with Gobby fish. They are a bit territorial at the beginning when they are building their tunnels. Moreover, their aggression is also visible when their tank mates are small and slow fish. Otherwise, you will always watch them silent and busy with their burrow.

Will They Break the Tank Glass or Eat Fish in the Tank?

They produce high heat and bubble cavitation at 60 mph. However, they don’t affect the aquarium glass and other creatures as well until other creatures try to prey on them. Moreover, they don’t eat other fish until the subject is small and slower.
